To all urk-om it lmay concern.:

' Be it known that I, FREDERICK Janine Wasi', of the city of Winnipeg, in the Prov- `ince of Manitoba, Canada, have linvented certain new and useful Improvements in Storage-Battery-Plate Separators, of which the: following'isthe specification.

The invention relatesv to improvements in ,storage battery plate separators, the present pendingV application No. 553032 filed the 15th day of application being a division of my April` 1922, for storage batteries. Y An object of the invention is to provide separators associated Vwith the positive electrodes or plates of the battery, the separa.-V

.tors not only positively separating the posi tive and lnegative plates butV preventing the y loosening and scaling olf of the active mal zo ' ot vthe battery plates. thereby permittingof the removal of the plates as a unitvand also.

terial of the positive plate andv thereby not only lmaterially increasing'the life of the positive plate but-also preventing the acbattery.' -A

Y A further object is to pro-vide a separator constructed to permit of the bolting together cumulation of sediment inthe bottom of the lpreventing any tendency of the plates to With the above Vmore important objects in "iewthe invention consists essentially in the arrangement and construction of parts here- A inafter more particularly described and later pointed out. in the appended claims, reference being had to the accompanying draw-l ing in which y Fig. 1 is aface view of one of the positive plates and enclosed Within my separator. l

According' to my invention A the positive and negative plates-of the battery are simif larly constructed with the exception that'th'e positite ed The 'cially separator.

-crel plates are enclosed within' nl fspefv 'tiveplates es 1 are of the usua grid formation with the paste or active materialY 2 cariled by the grid. The grid is supplied at the top with an extending terminal 3 and at one end with two spaced upper Iand lower Vum, serial no. 553,032. Divided and this application med apra s, ma. seran no. ascesa.

end lugs 4 and '5 and at the other end with a centrally spaced end lug 6, the lugs being provided with cross openings 7. These lugs are utilized for a.l purpose fully disclosed in my (3o-pending application hereinbefore referred to.

Centrally the grid ofthe plate or electrode A is supplied with an opening 8. The positive plate or electrode is enclosed within a ,perforatedacid resisting casing or envelope 9 formed in the present instance from celluloid, there being perforated sheets 10 andll of celluloid `at veach side of the'plate and connecting celluloid bands 12 spanning the edges of the plates and cemented to the edges of the side sheets. The lugs and the ter# lninal protrude through the envelope. Y

Between the side sheets of the envelo e" and the grid I insert asbestos or such li e sheets or pads 13 and 14. A central celluloid or such like acid resisting ferrule 15 passes through the opening '8 of the grid and eiectively hold the' envelope sides inv `through the pads and the side sheets and tive terminals. They are also supplied with a central opening corresponding to that 8 of the positive plates. l Accordingly after` the positive4 and negative plates have been assembled in the usual manner they can be bolted together by passing celluloid or such like acid resisting bolts through the central openings of all plates.

This firmly holds the plates together, allows l them to be lifted as a unitand prevents any tendency at buckling of the plates.

The separator which I provide for the positive plate entirely encases the same whilst allowing of the eective action of the 'electrolyte on the plate. There is no pos-- Vsibility ofV internal short circuiting as the separator positively separates thenegative from the positive plates and the very nature of the separator is such that the active ma.-

terial of the plates is positively prevented from loosening and scaling ott'. A further feature is that there is no possibility of sediment accumulating in the bottom of the battery employing my plates.

What I claim as my invention is 1. In combination, a positive electrode having a central transverse opening therein, perforated celluloid plates positioned at the sides of the electrode, Celluloid bands connecting the plates and cemented thereto, the bands enclosing the sides and ends of the electrode, asbestos pads inserted between the plates and the electrode and a ferrule passing through the opening in the electrode and through the pads and side plates and having the ends cemented to the side plates` such ferrule providing an opening for fastening'` means to connect several similar plates.

2. In combination, a positive electrode having a central and other suitably positioned openings therein, asbestos pads covering and engaging the sides of the electrode, pert'orated Celluloid plates covering the outer sides of the pads, Celluloid bands-enclosing all sides of the electrode and cemented to the edges of the Celluloid plates, a ferrule passing through the central opening and having flared ends cemented to the side plates and Celluloid ins passing through the other openings and) cemented to the side plates. said pins holding the side plates and pads against the electrode and said ferrule providing an opening for attaching means passing therethrough to connect several of such electrodes together.
